The Lowdown
Right then, let’s have a look at what’s on the cards for us here.
To be straight with you, the next week or so is pretty quiet. We’ve got tiny, weak swell and mostly onshore or cross-onshore winds, so don’t bother paddling out until we get to the second week. From the 11th of August right through to the 19th, it’s a real struggle – tiny waves, poor conditions, and nothing to get excited about. The water temp is sitting at 74°, which is a touch warmer than normal for this time of year, so at least you won’t need a thick wetsuit while you’re waiting.
The real action starts to show on the 20th of August. Thursday morning at Tarnos - La Digue sees a clean, cross-offshore breeze from the NE at just 3 mph, with a 5 ft NW swell. The combined energy hits 575 (moderate), and the period is 8 seconds – not the longest, but it’ll be peeling nicely. This is the first proper standout of the forecast.
Then, the absolute highlight lands on Monday the 24th of August. Early morning, glassy conditions with zero wind, a 8 ft NW swell, and the combined energy is pumping at 882 (strong). That’s a solid, powerful groundswell with a 9-second period. It’s going to be clean, well-shaped, and with that much energy, you’ll feel the push. This one is for the experienced crew – it’s pushing 8 ft, so it’s a bit much for beginners.
But the real gem might be Tuesday the 25th of August. Early morning, glassy again, with a 8 ft NW swell arriving from the same direction. The combined energy is 1077 (strong to very strong), and the period is 10 seconds. That’s excellent surf for experienced surfers – clean, powerful, and with long gaps between sets, making the paddle out a bit easier. This is the best window of the whole forecast.
After that, we’ve got a couple of marginal days, but nothing to write home about. The 26th is a bit messy with rain showers and a cross-shore wind, but the swell holds around 6 ft.
So, in short: wait out the first week, then get ready for the 20th, but the 24th and 25th of August are your true standouts. Crowds are possible at Tarnos, so get there early.
